ROS ASSY HARNESS ASSY MAIN

PWBA MCU LV/HVPS
Step Check Yes No
1Check of ROS ASSY attachment
Re-attach ROS ASSY. (p.375)
Does the error recur when the power is turned
ON?
Go to Step [2]. End of
procedure
2
Continuity check of HARNESS ASSY MAIN
Remove ROS ASSY. (p.375)
Disconnect the P/J407 from PWBA MCU.
Is the continuity normal between all terminals
of J407 ↔ J601?
Go to Step [3]. Repair broken
or shorted part.
35 VDC power supply check to ROS and
PWB SOS
The voltage of P407-16 ↔ P407-14 on
PWBA MCU is 5 VDC?
Go to Step [4]. Go to Step [6].
4Check after replacement of PWBA MCU
Replace PWBA MCU. (p.404)
Does the error recur when the power is turned
ON?
Go to Step [5]. End of
procedure
5Check after replacement of ROS ASSY
Replace ROS ASSY. (p.375)
Does the error recur when the power is turned
ON?
Go to FIP-1 81
Electrical noise. End of
procedure
65 VDC power supply check to PWBA MCU
The voltage of P410-3 ↔ P410-4 on PWBA
MCU is 5 VDC?
Replace PWBA
MCU. (p.404) Go to Step [7].
7
Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-3 ↔ J502-3
J410-4 ↔ J502-4
Replace LV/
HVPS. (p.407) Repair broken
or shorted part.
Step Check Yes No
